| Packet transmission network is the new metro broadband transmission network isadapted to transmit a wired or wireless telecommunication services，television anddata transmission services of the unified platform，is consistent with the basis of therequired transmission NGN.With full-service network IP development,all IP-basedtransport network is the general direction of future development.PTN technology hasbecome a local and metro transport network evolution to IP mainstreamtechnology,one of the existing network to get a large number of applications.The main purpose of this study is to make himself units and willow NetworkMaintenance Centre packet transport network during construction,better able toimprove the level of expertise,network maintenance level.Through research andanalysis of key indicators system,and further master the system construction andmaintenance work late,so that in the future be able to carry out a very thorough jobpacket transport network construction and maintenance work.The main research method is to use theoretical analysis and practical test andmeasurement results are integrated way of comparison.First of all importantparameters of the system indicators: network node,the core layer,convergence layerand access layer,business and family needs analysis and research.Explain itssignificance in practical work,and then work through the use of fieldmeasurements,the test results obtained for analysis.Through the index testanalysis,pointing out its influencing factors,adjusting related parameters andsettings,observation of the test results.Ultimately identify the best network-buildingprograms.Through theoretical analysis of system metrics and practical test andmeasurement,making the original system parameters has been furtheroptimized,system parameters has been further improved anti-jamming performancestrengthened. Final completion of the laying area in willow packet transportnetwork,and optimize the integration of the existing network. |
